The thermal conductor 11 is embedded inside the pillar 7, and also canadhere tightly outside the pillar 7 certainly. The other side of thepillar 7 is connected with the base 8, and the base 8 is connected withthe shoulder on the inner wall of the thermal receptor 6 so as to playsupport effect. The outside of the thermal receptor 6 is set with heatresource 10.

As shown in FIGS. 2 and 3, the split-flow piece 4 is set with severalliquid-connecting groove 41, and the high-pressure liquid enters theliquid-connecting groove 41 through the inflow pipe 2. The obstruct-flow5 is contacted with the split-flow piece 4, and there are severaloutward convex 51 and concave 52 on the periphery of it.

The out edge of sad convex 51 props on the inner wall of the thermalreceptor 6, and the liquid inside the liquid-connecting groove can enterthe side of the pillar 7 through the concave 52. The tiny channels areset between the pillar 7 and the thermal receptor 6, and inside the tinychannels, the high-pressure water is heated to generate high-temperaturesaturated water.

The tiny channel includes the gap 71 between the outer surface of thepillar 7 and the inner surface of the thermal receptor 6, and the widthof the gap is less than 1 mm.

Alternatively, the tiny channel includes the several thin groove 72 onthe outer surface of the pillar 7, and the width of the thin groove isless than 1 mm and the depth of it is less than 1 mm.

Certainly, the tiny channel can also includes the gap 71 and the thingroove 72 meantime, and it has been proved by many experiments over andover again that the effect of generating steam of the system is the bestwhen the tiny channel includes the gap 71 and the thin groove 72meantime along with the gap 71 is less than 1 mm.

The high-pressure liquid enters the inflow pipe 2 through the liquidpump 1, split by the split-flow piece 4, obstructed by the obstruct-flowpiece 5, and then enters the tiny channel and heated in the narrow spaceof the tiny channel to form high-temperature and high-pressure saturatedwater. After formed, the high-temperature and high-pressure saturatedwater is sprayed out from the tiny channel by high pressure and thenforms tiny saturated water particles and hit the high-temperature statedsaturated water explosive device and then occurs water explosion,quickly intensive evaporation and formation of high-temperature andhigh-pressure steam.

The saturated water explosive device includes porous material body 9,and the porous material body is placed inside the cavity of the thermalreceptor 6 and placed on the end close to the steam exit 13. The porousmaterial body 8 may be net structure. The outer side of the steam exit13 is connected with power conversion device 14, and can be cylinder orsteam turbine to work outwardly to generate power output.

The outside of the thermal receptor 6 is heat source 10, and the heatsource 10 can be heat energy generated by burning fuels and can be wasteheat energy with suitable temperature, and can be heat energy saved byphase-changed heat accumulator, etc. The outside of the heat resourcecan be covered by thermal insulation layer 15.

A method of generating steam power of the invention comprises the stepsas follows: making high-pressure liquid generate high-temperaturesaturated water; making the high-temperature saturated water explodeinstantly when heated, so as to form the high-temperature andhigh-pressure steam flow.

We all known the process of vaporization of water, for instance, putting1 kg, 0° C. water into the container with piston, and heating thecontainer from outside, and keeping the pressure inside the container isp invariantly. At the beginning, the temperature of the water isgradually increasing, and the volume is increased slightly. But afterthe temperature is risen to ts corresponding to the saturatedtemperature of p and the water converted to saturated water, keepheating, then the saturated water changed gradually into saturatedsteam, i.e., so-called vaporization, until the ending of vaporization.During the whole process of vaporization, the temperature is kept at thesaturated temperature ts. During the process of vaporization, thespecific volume usually increased a lot due to the increasing volume ofthe saturated water. Keeping heating, the temperature begins to increaseagain, and the specific volume is continuously increased, and thesaturated steam is converted into overheating steam. When water meetsthe high-temperature object, the explosion occurred. Due to thesaturated water is in the high-temperature saturated state (criticalpressure pc is 22.064 MPa, critical temperature tc is 373.99 ° C.), withthe stronger ability of vaporization compared with unsaturated water,less absorption of heat, faster vaporization, and can generatehigh-temperature and high-pressure steam flow when exploded instantly.And for steam, it only expanded when heated, not exploded when meetingwith high-temperature objects.
